You're going to need a lot of bots for this.
Basically:
1) Load bots into the servers you want to notify
2) Scan update packet for new realm portals
3) Move a bot to the location of the new realm portal
4) Obtain the portal ID and use the portal packet to enter the realm
5) Have it return or print something every time there is a new quest or when Oryx says something (idk the packets to this)
